OF NEW YORK, N. Y., A CORPORATION F NEW JERSEY COMPO'U'ND LINI'NG MACHINE Application led September 26, 192'?. Serial No. 222,025.

This invention relates in general to a compound lining machine for can ends, and has more particular reference to a continuously operating machine in which the lining compound is applied by means of a roller to a die which passes over the roller, the die directly transferring a gasket of the compound to 21 can end.

In the manufacture of a sanitary tin can of commerce the end seams of the can are providedby'flanging the can body and olfsetting the edge of the can end to provide a com anion flange and interfolding and pressing t ese flanges together to form an hermetic seal, gasket material is interposed between them in the form of a film of desired thickness upon the can end flange.

This invention contemplates the provision of a gasket material upon a die adapted to engage about the shoulder of the can end formed in offsetting to provide the flange and i to deposit on this flange a formed liner of semi-solid gasket material or compound which is received from .a roller running in a supply of the material.

An important obj ect of the invention is the provision of an apparatus for thus applying the gasket which will arrange the material upon the can end iange'with minimum movement or disturbance of the die after it receives its charge.

Any important object of this invention, therefore, is in the provision of continuously operable carriers forl the can ends and dies which register in vertical alignment and are relatively movable to apply a gasket directly from a die which receives the compound to a can end placed below it.

A further important object of the invention is in the provision of a die fixed against rotation upon its own aXis and moved Without interruption over a roller which applieslining compound to the entire die surface without independent rotation thereof.

A further object of the invention is in the provision of a die moved without independent rotation about a vertical axis and lixed in height, to which lining compound is applied, and thereafter a can end to be lined is raised without interrupting the movement of the die about the axis. r A still further object of the invention i in the provision of a lining die supported by a continuously moving carrier, which engages a compound applying roller to receive a gasket in axial alignment with a can end subsequently positioned and later moved relaijv'ely to receive the lining gasket from the Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

In carrying out this invention, can ends are separated from the bottom of a stack, picked up one at a time by a rotating feeding turret and delivered continuously to can end supports in a rotating carrier disposed below raised lining dies. After a rotatable compound applying roller engages the entire lining surface of the die without independently rotating it, the positioned can end is raised detail section of the compound I toward the die, lined with a gasket, stripped from the' die, moved downwardly and stripped from the can support. A discharge turret then engages and continues the movement of the lined can end,l delivering it to a conveyor for further operations.

.. Referring more particularly to the drawings, a supporting frame 20, in the form of a housing,;is mounted on a base 21, and has an lo table 23. The driving mechanism contained within the housing comprises a horizontal drive shaft 24 driven by a sprocket 25 secured to the shaft, and a drive chain 26, which also.

engages a sprocket 27 secured to the rotor shaft 28 of a motor 29.

A worm 30 carried by drive shaft 24 meshes with a worm gear 31 secured to the lower end of a vertical shaft 32 journalled in bearings 20 33 and 34 formed in a gear casing 35 secured to the under side of the web 22 and in a bearing 36 formed in the web and the bearing 37 formed in the table.

Directly above the bearing 36 in the web 22, w a spur gear 38 is keyed to the shaft 32, which has an upwardly extending hub 39 with a bevel gear 40 meshing with a bevel pinion 41 at the end of a stub shaft 42 journalled in bearing 43 of the housing. The opposite end 30 of the stub shaft 43 carries-a bevel gear 44 l.

which meshes with a bevel pinion 45 on a'vertical stub shaft 46 journalled in a bearing 47 of the housing. At the upper end of shaft 46 is a can end separating device comprising a .i5 cutout disc/4 8 with a spiral groove 49 which engages the periphery of the lowermost can end 50, which is held within a magazine 51. The can ends 50 are formed with vertical shoulders 50 to fit within the can bodies and with flanges 502 which are usually in the form of channels. rIhe can ends are stacked in a magazine 51, which comprises supporting rods, 52 mounted above the table 23. The stack of can ends 50 in the magazine eX- tends above a can end feeding turret 53 secured to the upper end of shaft 32 and movable over the surface of the table 23. The turret 53 is provided with a series of can end pockets 54 (see Figs. 1 and 4) at the rear side o of which is a finger 55 extending up forengaging the lowermost can. end separated'from the magazine stack by the cut-out disc 48, this can end being then supported upon the disc 48 and upon a shoulder 56 at the opposite side u of the magazine, so that it may be swept around by the finger 55 in a circular path of travel in one of the pockets against an outer circular guide 57. The can ends are thus disengaged one at av time from the bottom of the 60 stack and are fed successively in properly timed relation by the feeding turret 53.

From the feeding turret 53, the can ends are delivered successively without interruption to a rotatable carrier, which comprises a 5 turret sleeve 60 surrounding a fixed bearing intermediate web 22 and a top horizontal ALacasse post 61 secured to the web 22. The sleeve 60 is continuously rotated by means of a spur gear 62 secured to or formed integral with the lower end thereof and meshing with the spur gear 38 keyed to the shaft 32.

Projecting from the sleeve 60 is a spider section 63 having outer tubular bearing 64 in which can end supports 65 are feathered by keys 66 for vertical sliding movement.

Each can end 50 is delivered to a support 65, which comprises an enlarged head 66 (see also Fig. 7) which' carries a cap end supporting plate 67 secured loosely to the head by a clamping block 68 with coil springs 69 seated in a recess in the head and interposed between the head and the plate 67 to permit a yielding of the plate.

ntermediate the ends of sleeve 60 it carries a perforated plate 70, the upper surface of which is flush-with the table 23. Openings 71 are provided through the plate to permit movement of the can end supports 65 and the heads 67 therethrough, but the openings are not of sufficient size to permit the passage of can ends 50. As the can ends -are fed by turret 53, they are slid over the surface of the plate in engagement with the can end supports 65, and during the removal of the can e-nd the upper surfaces of the plate 67 carried by the can end support 65 is fiush(` with the upper surface of the plate 70, thus permitting a sliding movement of the can ends from the plate.

To raise and lower each can end support 65, a cam roller 72 is mounted at the lower end of each support 65 and is adapted to ride upon a cam surface 73 formed in a circular cam 74 arranged on the web 22 (Fig.

Since the cam is stationary and the can end supports 65 rotate witlithe carrier, each can end support is raised and lowered as the timed actions of the machine require.

Lining dies 75 corresponding in number to the can end supports 65 are mounted in alignment above the supports 65 and in bearings 76 at the outer ends of spider arms 77 projecting from the upper portion of the turret sleeve 60. In each bearing 76 there is a sleeve 78 vertically adjustable within the bearing by nuts 79 threaded on the upper and lower ends of the sleeve. The lining die 75 is threaded on or otherwise fixed to the lower end of the sleeve and is thus accurately adjustableA in fixed position in its bearing 7C. The die is annular in form so as to pass around the shoulder 50 of the can end. y

The lower edge ofthe lining die receives a semi-liquid lining compound upon its lower annular surface, which conforms to the size and shape of the flange of the can end 50 to be lined, and subsequently transfers this ring of compound into the can end fiange.

To apply a lining compound 80 to the lower surface of the die, a lining receptacle or tank 81 (see Figs. 1, 5 and 6) is secured on the upv j per surface of the table 23 and contains a continuously rotating roller 82 secured to one end of a horizontal shaft 83 journalled in a bearing 84 formed integrally with the tank 8l. This roller is supported between the die and the carrier. At its outer end, the shaft 83 carries a bevel gear 85 which meshes with a corresponding gear at the upper end of a vertical shaft 87 journalled at its upper end in the frame of the tank 81 and in a bearing 88 formed in the web 22 at its lower end. A spur gear 89 secured (see also Fig. 2) to the shaft meshes with an idler gear 90 mounted on a stud shaft 91 secured to the web 22, and this gear meshes with the driving gear 62 formed as a part of the turret sleeve 60. A. continuous rotation is thusimparted to the roller 82 partially immersed in the compound 80, which raises a film of compound on the surface of the roller gaged in thickness by the scraper plate 92 adjustable by screws 93.

' As each die 75 is rotated by the turret sleeve 60 so that adjoining portions of the roll and die travel at like speed in the same direction, the die moving tangentially to the roll, the annular lower surface of the die engages and passes over and across the upper surface of the roller 86, which applies an annular film or ring of compound of predetermined thickness to the die surface. The compound is applied j ust prior to the positions where the can end support 65 receives a can end 50 from the` can end feeding turret 53.

The dies 75 remain xed in their vertical position as they are rotated by the carrier turret, and the can ends are moved toward and from their respective dies without interruption'of the rotary movement. Just before a can end reaches the lining applying position, itis engaged and pressed firmly in engagement with the plate 67 of its support by means of a plate 94 secured to the lower end of a rod 95 movable slidably within sleeve 78 and carrying a block 96 (see Figs. 3 and 9) at its upper end. This block carries a cam following roller 97 confined within a cam groove 98 of a stationary cam 99 secured to the upper end of the `fixed support by a fastening nut 100, the sides of the block 96 having extensions 96 which engage the outer surface of the stationary cam 99 to prevent rotation of the rod 95. The upper edge of the plate 67 is preferably formed with a grooved edge or recess 101 for permitting the plate to engage under the can end flange and within the central portion of a can end positioned upon the can end support, and when the support is raised with a can end thereon, the can end is first engaged andv vpressed lirmly upon the plate 67 against the yielding pressure of spring 69 by means of the plate 94. At this time the plate 94 is projected below its die 75, as clearly shown Yin Figs. 3 and 8.

A continuation of the movement of the carrier turret brings the can end 50 in engagement with its corresponding die 75 to receive therefrom the lining compound, as'shown in Fig. 7, and as the can end support is withdrawn from the die 75, it is first stripped from the die by an ejecting movement of the rod 95 and plate 94 downwardly, so that the lined can end will not adhere to the die.

A further rotary movement of the carrier turret carries the can end supportdownwardly due to its contact with the cam 73, until the projecting edge of the can end 50 engages the perforation 71 in the plate 70, thereby stripping the can end from its support 65 and allowing the can endto rest on the upper sur-v face of the plate 70.

A discharge turret 101 is mounted at the upper end of a shaft 102 (see Figs. 1, 2, and 8) and the shaft is rotated by a gear 103 which meshes with the gear 62 of the driving sleeve 60, so the turret'` is constantly driven in timed relation to the lined can ends.

This discharge turret has can end pocket-s 104 andarms 105 to engage a lined can end 50 as it is moved in its circular path by the can end support 65, and one of the arms 105 engages behind the can end and sweeps it from the plate 70 across the surface of the table 23 against a circular guide rail 106 to a discharging position, where an opening 107 is provided in the table of sufficient diameter to permit the lined can end to fall through the table and upon a conveyor chain 108, which passes at one end over a sprocket 109 and moves in a discharge chute 110 for delivering lined can ends to a drier or to any other operating mechanism, which is not shown. To insure the discharge 0f a can end from the pocket 104 of the discharge turret 101, a segmental guide rail 111 mounted on the table 23 and forming an extension of the guide rail 106 is curved inwardly about a portion of the edge of the discharge opening 107.

All of the various operations take place in proper sequence without any interruption in the movement of a can end from the time it is fed from the magazine 51 until it is discharged upon the conveyor chain 108. The movement of the-can ends is continuous, the machine containing a number of can ends,

each being in a different stage of operation at i' any particular time.

It is thought that this invention and many of its attendant advantages will be understood from the foregoing description, and itv will be apparent that manychange's may be made in the form, construction and arrangement of the parts without departing from the spirit and scope ofthe invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
